Frequently asked questions
Answers to the things researchers ask us most. Don’t see yours? Get in touch.
Are your products for human use?
No. All products are sold strictly for in vitro laboratory research and development use only — not for human or veterinary use, and not evaluated by the FDA.
Do you provide a Certificate of Analysis?
Yes. Every lot ships with a full COA, and we publish certificates so you can match the report to the lot number on your vial.
How are the peptides tested?
Each lot is independently tested at an accredited U.S. laboratory by HPLC for purity and LC-MS for identity before it is listed.
How is my order shipped?
We offer FedEx Express 2-Day cold shipping with refrigerated, temperature-controlled pickup. Fulfillment is Monday–Friday, excluding holidays. Transit starts after dispatch; processing time is separate. Free shipping over $250. See our Shipping page for details, and contact us before ordering if you require special handling.
How should peptides be stored?
Store lyophilized vials cold and away from light. Reconstituted peptides should be refrigerated and used within the documented window.
What is your return policy?
Because these are sensitive research materials, see our Returns & Refunds page for full details.
Do you offer wholesale pricing?
Yes — labs and institutions can apply on our Wholesale page.
